GLFW_MAXIMIZED hint not working correctly #780

On Windows the GLFW_MAXIMIZED hint does not always work - whilst it works reliably when the app is launched from a console or via an IDE double clicking the exe in Explorer results in a normal sized window. However, calling glfwMaximizeWindow(window) after window creation works correctly.

This has been tested on the example boing as well as other code, issue first reported on the glfw forum by user luis.

So the easiest fix I can think of is to do

ShowWindow(_glfw.win32.helperWindowHandle, SW_HIDE);

at init to make subsequent calls ignore the STARTUPINFO without workarounds.
